To improve recommendation quality, the existing trust-based recommendation methods often directly use the binary trust relationship of social networks, and rarely consider the difference and potential influence of trust strength among users. To make up for the gap, this paper puts forward a hybrid top-N recommendation algorithm that combines mutual trust and influence. Firstly, a new trust measurement method was developed based on dynamic weight, considering the difference of trust strength between users. Secondly, a new mutual influence measurement model was designed based on trust relationship, in light of the social network topology. Finally, two hybrid recommendation algorithms, denoted as FSTA(Factored Similarity model with Trust Approach) and FSTI(Factored similarity models with trust and influence), were presented to solve the data sparsity and binarity. The two algorithms integrate user similarity, item similarity, mutual trust and mutual influence. Our approach was compared with several other recommendation algorithms on three standard datasets: FilmTrust, Epinions and Ciao. The experimental results proved the high efficiency of our approach.

In the Internet age, how to dig out useful information from massive data has become a research hotspot. The emergence of recommendation algorithms effectively solves the problem of information overload, but traditional recommendation algorithms face problems such as data sparseness, cold start, and low accuracy. Later social recommendation algorithms usually only use a single social trust information for recommendation, and the integration of multiple trust relationships lacks an efficient model, which greatly affects the accuracy and reliability of recommendation. This paper proposes a trust-based approach. Recommended algorithm. First, use social trust data to calculate user trust relationships, including user local trust and user global trust. Further based on the scoring data, an implicit trust relationship is calculated, called rating trust, which includes scoring local trust and scoring global trust. Then set the recommendation weight, build the preference relationship between users through user trust and rating trust, and form a comprehensive trust relationship. The trust relationship of social networks is integrated into the probability matrix decomposition model to form an efficient and unified trusted recommendation model TR-PMF. This algorithm is compared with related algorithms on the Ciao and FilmTrust datasets, and the results prove that our method is competitive with other recommendation algorithms.

The inhabitants of historic blocks require more social and planning consideration. A basic means to achieve inclusive planning and social sustainability in such areas is to quantitatively study the social integration of their inhabitants. Based on social survey data for the inhabitants of Harbin’s Central Street and DaoWai historic block in China, this paper establishes the measurement factors that affect inhabitant social integration to construct a measurement model. Statistical analysis is performed using exploratory factor analysis (EFA) and confirmatory factor analysis (CFA). The analysis results reveal five dimensions of inhabitant social integration: behavioral integration, cultural integration, industrial integration, spatial integration, and management integration. Subsequently, the statistical scores for social integration and related factors are calculated. The empirical results indicate that the level of the inhabitant social integration has an impact on the vitality and sustainable development of the blocks. The social integration score of the inhabitants of Central Street is higher than that of the inhabitants of the DaoWai historic block. Among the five dimensions, the industrial integration level of Central Street is the highest, whereas the spatial integration level of DaoWai historic block is the highest. The level of management integration is the lowest for both blocks. The difference in the levels of industrial integration between the two blocks is the highest, and cultural integration is the lowest. Comparing the status quo of the two blocks, the paper concludes that the promotion of inhabitant social integration requires enhancing the dimensions with lower measurement scores according to the specific conditions of the block. In this manner, a fundamental theory for a socially inclusive revitalization of historic blocks is established, thus to enhance social sustainability.

Historical, in addition to having auxiliary science in his knowledge, history also establish relationships with other sciences, especially fellow social sciences. In this connection what happens is a relationship of mutual need, herein lies the difference with the concept of science Auxiliary history, where a more dominant history in need of help to uncover a problem, more precisely we can call it with a combination of two social sciences. The development of post-World War II History shows a strong tendency to use the social sciences approach in historical studies. One of the basic ideas is that: the descriptive-narrative history is no longer satisfactory to explain complex problems or symptoms in the event of History. Psychology is very related to mental and psychological human. Humans who become the object of historical study is not just explained about the actions taken and what is caused by the action? why someone does that action? These questions pertain to the psychological condition in question. Conditions that can be caused by stimuli from the outside or the environment, can also from within himself. The use of social phsychology in history, gave birth to the focus of the study of the history of mentality.

O presente artigo fundamenta-se no pensamento de Foucault, Labov e Boudieu. Objetiva relacionar língua e sociedade, mostrando que a sociedade humana não se constitui sem a linguagem, da mesma forma que a língua não se realiza fora das relações sociais. A relação entre língua e sociedade apresenta influência mútua, pois através da linguagem se participa das relações sociais de poder e as mudanças na estrutura social são decorrentes da dinâmica dessas relações. A língua não é um corpo autônomo capaz de determinar as relações sociais, como também não é determinada pela estrutura social, mas há uma relação de influências entre elas, por isso que pela análise linguística pode-se compreender elementos importantes da estrutura social, como também pela análise das relações sociais pode-se compreender muito dos processos linguísticos. A língua não está deslocada de um contexto sociocultural, sua significação é decorrente de seu contexto de produção, sua força simbólica se potencializa a partir da força do grupo social que a produz. A língua, assim como a sociedade, não é um corpo estático, há transformações significativas no decorrer do processo histórico, a mudança linguística não ocorre isolada do movimento de classe, muito embora ela não seja determinada por ele, há uma relação entre a mudança linguística e o movimento de classe, em que este só se completa quando ocorre a mudança linguística e, ao mesmo tempo, ela é um reflexo do movimento de classe. Assim, não se pode negar a relação de influências mútuas entre língua e sociedade.  Palavras-chave: Língua. Sociedade. Contexto sociocultural.Language and Society: mutual influences in the sociocultural construction processABSTRACTThis paper is based on the thought of Foucault, Labov and Boudieu and aims to relate language and society, showing that human society is not formed without the language, in the same way that the language is not out of social relations. The relationship between language and society presents mutual influence, since from the language we participate in the social relations of power and changes in the social structure itself are resulting from the dynamics of these relationships. The language is not a body as able to determine social relationships, nor is determined by social structure, but instead there is a relationship of influences between them, so that the linguistic analysis can understand important elements of the social structure, as well as the analysis of social relationships can be understood much of linguistic processes. The language is not shifted from a sociocultural context, its meaning is due to its context of production, as well as its symbolic force leverages from the strength of the social group that produces. The language, as well as society, is not a static body, there are significant changes in the course of the historical process, and language change does not occur in isolation from the class movement, although it is not determined by the class movement, there is a relationship between linguistic change and movement class, in that the movement of class only complete when the language change and at the same time, the language change is a reflection of the class movement. So, there's no denying the relationship of mutual influences between language and society.    Keywords: language. Society.

Abstract. Background: Monitoring of suicide rates in the recovery phase following a devastating disaster has been limited. Aim: We report on a 7-year follow-up of the suicide rates in the area affected by the Great East Japan Earthquake, which occurred in March 2011. Method: This descriptive study covered the period from March 2009 to February 2018. Period analysis was used to divide the 108-month study period into nine segments, in which suicide rates were compared with national averages using Poisson distribution. Results: Male suicide rates in the affected area from March 2013 to February 2014 increased to a level higher than the national average. After subsequently dropping, the male rates from March 2016 to February 2018 re-increased and showed a greater difference compared with the national averages. The difference became significant in the period from March 2017 to February 2018 ( p = .047). Limitations: Specific reasons for increasing the rates in the recovery phase were not determined. Conclusion: The termination of the provision of free temporary housing might be influential in this context. Provision of temporary housing was terminated from 2016, which increased economic hardship among needy evacuees. Furthermore, disruption of the social connectedness in the temporary housing may have had an influence. Our findings suggest the necessity of suicide rate monitoring even in the recovery phase.

This article covers several stages of the work of Pichon-Rivière. In the 1950s he introduced the hypothesis of "the link as a four way relationship" (of reciprocal love and hate) between the baby and the mother. Clinical work with psychosis and psychosomatic disorders prompted him to examine how mental illness arises; its areas of expression, the degree of symbolisation, and the different fields of clinical observation. From the 1960s onwards, his experience with groups and families led him to explore a second path leading to "the voices of the link"—the voice of the internal family sub-group, and the place of the social and cultural voice where the link develops. This brought him to the definition of the link as a "bi-corporal and tri-personal structure". The author brings together the different levels of the analysis of the link, using as a clinical example the process of a psychoanalytic couple therapy with second generation descendants of a genocide within the limits of the transferential and countertransferential field. Body language (the core of the transgenerational link) and the couple's absences and presence during sessions create a rhythm that gives rise to an illusion, ultimately transforming the intersubjective link between the partners in the couple and with the analyst.
